Embodiment
Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is done and describes clearly and completely further.
Embodiment
Shown in composition graphs 1 and Fig. 2: the device of a kind of Rapid Screening metalwork planarity defects that the present embodiment provides, comprise base 1 and conducting metal platform 2, described conducting metal platform 2 is provided with detection zone 21, in described detection zone 21, be provided with some metal floating contacts 3, the conducting metal platform 2 being positioned at periphery, detection zone 21 is provided with some pilot lamp 4; On described metal floating contact 3 all insulate and is located in detection zone 21 conducting metal platform 2, and be all arranged with spring 5 being positioned on the metal floating contact 3 below conducting metal platform 2, the bottom of described spring 5 is all inconsistent with the conductive metal sheet 6 be located on base 1 surface, described conductive metal sheet 6 is electrically connected with a pilot lamp 4 respectively by plain conductor, all pilot lamp 4 are all electrically connected by the positive pole of plain conductor with power supply 7, and the negative pole of described power supply 7 is electrically connected with conducting metal platform 2 by plain conductor.
In its natural state, the peak of described metal floating contact 3 is positioned at the upper limit position of metalwork flatness to be checked, that is: the upper end of described metal floating contact 3 is higher than the conducting metal platform 2 in detection zone 21, and height difference △ h is between the two the limits of error value of metalwork flatness to be checked; The distance values d of the lower end distance conductive metal sheet 6 of described metal floating contact 3 is the limits of error value of metalwork flatness to be checked.
Preferably: described metal floating contact 3 comprises top 31, middle part 32 and bottom 33, the middle part 32 between top 31 and bottom 33 forms boss, thus it is spacing to reach described spring 5.Between the surface of contact of described top 31 and conducting metal platform 2, be provided with insulation sleeve 8, between the surface of contact of described middle part 32 and conducting metal platform 2, be provided with insulating mat 9, to avoid the formation of short circuit, affect test accuracy.Described pilot lamp 4 is LED, to realize energy-conservation and to increase the service life.
The principle of work of device described in the utility model is as follows:
Due in its natural state, the peak of described metal floating contact 3 is positioned at the upper limit position of metalwork flatness to be checked, that is: the upper end of described metal floating contact 3 is higher than the conducting metal platform 2 in detection zone 21, and height difference △ h is between the two the limits of error value of metalwork flatness to be checked; The distance values d of the lower end distance conductive metal sheet 6 of described metal floating contact 3 is the limits of error value of metalwork flatness to be checked; Therefore, if tested surface flatness is in the error range of regulation, then when metalwork to be checked is placed on detection zone 21, tested surface can contact with the metal floating contact 3 of its relevant position, thus make metalwork and form conducting loop between metal floating contact 3, spring 5, conductive metal sheet 6, pilot lamp 4, power supply 7 and conducting metal platform 2, pilot lamp 4 is lighted, represents that the flatness of institute's detection faces meets the requirements; On the contrary, if tested surface flatness is beyond the limits of error value of regulation, then when metalwork to be checked is placed on detection zone 21, tested surface can not touch the peak of the metal floating contact 3 of correspondence position, thus also just can not conducting metalwork and the circuit loop between metal floating contact 3, spring 5, conductive metal sheet 6, pilot lamp 4, power supply 7 and conducting metal platform 2, pilot lamp 4 is not worked, represents that the flatness of institute's detection faces is undesirable.
During actual use, according to the quantity of the size adjustment metal floating contact 3 of metalwork to be checked and sectional area, also these metal floating contacts 3 can be replaced with the metal floating contact 3 that has larger detection plane.In addition, in testing process, on detection zone, gently can move metalwork to be checked to detect the flatness at its diverse location place.
Visible in sum: to use device described in the utility model, only metalwork to be checked need be placed on detection zone, whether entirely bright by viewing lamp, can the flatness whether existing defects of intuitive judgment metalwork to be checked, not only simple to operate, quick; And structure is simple, affect little, testing result accurately and reliably by extraneous factor; Therefore, device described in the utility model can be used for carrying out Rapid Screening to the planarity defects of metalwork in enormous quantities, with ensure the product mass-energy of sale metalwork meet high precision matching requirements, there is obvious industrial application value.
Finally be necessary to herein means out: the foregoing is only the utility model preferably embodiment; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.
